       3. The cutter sharpener as claimed in  claim 1 , wherein each said support ( 20 ) further comprises an elastic deformation portion ( 23 ) connected between said sharpening block mounting portion ( 22 ) and said positioning section ( 25 ) of said support ( 2 ). 
     
     
       4. The cutter sharpener as claimed in  claim 1 , wherein each said mounting portion ( 13 ) of said receiving unit ( 11 ) comprises an angle indication ( 16 ); each said support ( 20 ) further comprises an angle indication ( 26 ). 
     
     
       5. The cutter sharpener as claimed in  claim 1 , wherein each said receiving unit ( 11 ) of said base ( 10 ) comprises two said mounting portions ( 13 ) arranged opposite to each other; two said supports ( 20 ) are respectively mounted in the two said mounting portions ( 13 ) of each said receiving unit ( 11 ) of said base ( 10 ). 
     
     
       6. The cutter sharpener as claimed in  claim 1 , wherein each said positioning section ( 15 ) of said mounting portion ( 13 ) comprises a positioning groove ( 151 ); said positioning section ( 25 ) of each said support ( 20 ) comprises a positioning head ( 251 ) matching said positioning groove ( 151 ) of one respective said positioning section ( 15 ) of said mounting portion ( 13 ). 
     
     
       7. The cutter sharpener as claimed in  claim 1 , wherein each said positioning section ( 15 ) of said mounting portion ( 13 ) comprises a positioning recess ( 152 ); said positioning section ( 25 ) of each said support ( 20 ) comprises a positioning lug ( 252 ) matching said positioning recess ( 152 ) of one respective said positioning section ( 15 ) of said mounting portion ( 13 ). 
     
     
       8. The cutter sharpener as claimed in  claim 1 , further comprising at least one pivot device ( 30 ) respectively pivotally connecting said pivoting portion ( 21 ) of each said support ( 20 ) to one respective said pivoting portion ( 12 ) of said receiving unit ( 11 ), wherein said pivoting portion ( 12 ) of each said receiving unit ( 11 ) of said base ( 10 ) comprises a rotation stopper surface ( 121 ); each said pivot device ( 30 ) comprises a pivot member ( 31 ), said pivot member comprising a rotation stopper surface ( 311 ) matching said rotation stopper surface ( 121 ) of said pivoting portion ( 12 ) of each said receiving unit ( 11 ) of said base ( 10 ). 
     
     
       9. The cutter sharpener as claimed in  claim 1 , further comprising at least one vacuum suction cup ( 50 ) mounted on said base ( 10 ), and at least one vacuum suction cup operating member ( 60 ) operable to drive said at least one vacuum suction cup ( 50 ) to suck to a surface.
